| | Re: Uv sterilizers and chelated iron precipitation problem
Diana Walstad, in her book, "The Ecology of the Planted Aquarium", says that intense UV or near UV light causes the iron in the water which is usually not bioavailable, to become bioavailable for a brief time, and might cause algae to grow much better. Algae has to get the iron it needs from the water, since it has no access to the substrate. Thus, this could make life easier for algae. I'm not sure how this relates to the UV breaking down chelators, if it even does. I'm thinking about trying to test this idea sometime in the next 6 months.
